Thanks. Have you bought any bulk lots of coins on eBay? I have been looking, but they are so unspecific... '1kg of mixed coin', I don't want to order something like that to end up with a big bag of pennies or euro coins! I have ordered a couple of small collections on eBay for a couple of UK Pounds. I went for listings that stated the coins in the image are the ones you'll receive, so I'll sort through that when they get here.
I currently have 35 different countries, but am cheating a little and including 7 euro coin variants lol. Small potatoes so far, but I'm keen to expand!
